摘要： Provided are electric safety valves and methods of use. An electric safety valve comprises an electric actuator positioned in an interior chamber of the electric safety valve; the interior chamber comprising a dielectric fluid and being pressure and temperature compensated with a flow passage extending axially through the electric safety valve. The pressure and temperature compensation is performed via a compensating subassembly in pressure communication with the interior chamber thereby providing a section-balanced electric safety valve. The electric safety valve further comprises a protective sleeve separating the interior chamber from the flow passage. The electric safety valve further comprises at least one compression spring rod coupled to a closure member capable of restricting or preventing fluid flow through the flow passage. A method includes actuating the electric actuator; the electric actuator being magnetically coupled to the closure member such that actuation of the electric actuator pivots the closure member.

摘要： Certain aspects of the present disclosure are directed to tools actuated by pipe swell. A downhole assembly for a wellbore may be provided. The downhole assembly can include a first sleeve and a second sleeve. The first sleeve can expand from a first position to a second position in response to a first pressure applied to the first sleeve. The first sleeve can contract to the first position in response to a cessation of the first pressure. The second sleeve can be positioned adjacent to the first sleeve to define a swell chamber. The swell chamber can actuate a downhole tool by a pressure stored in the swell chamber by the expansion of the first sleeve.

摘要： Surface controlled subsurface control valves for use in wells and methods of controlling the same. In one embodiment, a valve includes a valve body, a bore closure assembly, a mechanical linkage, a drive assembly, and a control assembly. The valve body defines a bore for fluid to flow through when the bore closure assembly is in an open position. When the bore closure assembly is in its closed position, the bore closure assembly prevents fluid from flowing through the bore. The mechanical linkage is operatively connected to the bore closure assembly and to the drive assembly. The primary control assembly determines a force to apply to the mechanical linkage based on a present operating condition of the valve and causes the drive assembly to apply the determined force to the mechanical linkage. As a result, the mechanical linkage drives the bore closure assembly.

摘要： A linear electromechanical actuator with a failsafe design may be used with a downhole flow control system. In one example, a subsurface safety valve for controlling flow of production fluids includes a valve closure element moveable between an open position and a closed position in response to a linear movement of an actuating member. A biasing member biases the valve closure element to the closed position. A power section with an electrically-powered motor drives a rotation. A drive section coupled to the power section converts the rotation of the motor to the linear movement of the actuating member to at least open the subsurface safety valve. A clutch selectively decouples the power section from the drive section in response to a power loss.

摘要： Linear actuators, motor assemblies, and methods to actuate a device or load are presented. A linear actuator includes a piston having a piston slot and configured to linearly shift from a first position to a second position, and rotate as the piston shifts towards the first position. The linear actuator also includes an activating lever having a shoulder that the piston engages as the piston shifts to the second position, where the activating lever is configured to shift after piston engages the shoulder. The linear actuator also includes a retractable rail configured to shift from a first position downwards to a second position, and having a tab positioned in a groove of the piston slot as the piston shifts from the first position to the second position.
